The present invention relates to fluid burners, and more particularly to a rotary type burner adapted for association with a boiler or furnace and which may employ oil, gas, a combination of oil andgas, or a colloidal medium for fuel. 7

' It is the primary purpose of this invention to provide a rotary type burner with means whereby the fuel and combustion supporting airwill be mixed in a most thorough manner and then forced. t'owardthe furnace in a definite flow-pattern,

Afurth-er object .of'th'is invention is to. provide a rotary burner of the present type withair blowing means effective tocause all of the combustions'upporting 'airto flow in .a definite pattern' atall times irrespective of the 'air ,lolowerspeed' or the capacity at which the burner is operating.

A more specific object of this invention is to, provide means for such .a'burher whereby the. combustion-supporting air may be forced without any interference into the combustion chamber thereof in a smooth, annular-shaped pattern with the fuel medium-being added to such air from a plurality of nozzles disposed substantiallyat right angles to the direction ofsaid airflow.

Another object of the presentinventipn .is to provide a burnerof'thepresent'type with a construction which is such that fuel atomizing means a ad y m h e rom without. the necessity "of dismantlingany portions of thefburil erunit. v I

Fig.7 is an enlarged section taken substantially along line l-J of Fig. 5. Burners of the present type are primarily adapted to use as a fuel natural gas,liqu id oil, or a combination of both. However, whenever a liquid {p el such as oil is used, it has been found most efficient to atomiz e such a liquid very'thoroughly before igniting the same. Steam under pressure ha 'becn cunda mos effi e n cheap e i m for such atomization, and the present invention contemplates the use of such a medium, but it is to be nder te d th t ot e gaseous ediums unier p essure c uld a o be employed. 7

A rotary type burner which is particularly adapted or burnin li uid o l is l us in Figs. 1 and 3 of the present drawings. Referring particularly to Figs. '1 and 3, one form of the present invention is incorporated in a burner unit comprisin a substantially cylindrical casing in which is adapted to be connected with a furnace or'boiler unit (neither of which isherein shown) as at. l I). A journal box I I' is rigidly secured within the central portion of casing H] by means of spider legs l2 "which projectradially from said journal box to be secured by means of bolts I 3 to an annular flange portion M of said casing. This journal boxl l is cored as at points l5 thereby to form a hollow jacket for receivin circulating cooling water which may gain entrance into said jacket by means, of an aperture l6 provided-in-the bottom of said jacket. A water overflow aperture l! is provided in the top portion of the jacket. The journal box is hollow and is provided at its opposite end portions with openings which are adapted'to-receive spaced ball bearing members t8 and IQ-in'which is rotatably journaled, coaxially ofsaid casing 10, a tubular shaft 20. A tubular spacer member -2| functions, in conjunction with elements 2?. and 2 3, to retain the bearings 18 and f9 in their proper positions. The spacerZl has formed thereabout an annular groove 24 adapted ofaplura'lity-of bolts 30, only one ofwhich is disit closed herein. Disposed within and coaxially of the tubular shaft is a second tubular shaft or steam conduit 3i which at its rear end is welded at 32 to a sleeve member 33 which in turn is forcefitted into the shaft 20 and secured to a hollow plug by means of a radially disposed pin 35. The hollow plug 34'extends out of the. shaft 20 to be rotatable within a bushing 35 carried rigidl yl within the housing 29. The forward end of the conduit 3i is welded, 'or otherwise suitably see,

cured, to a circular spider 31 which is force- This spider 31; in con I junction with the sleeve 33, secures shaft'ZO and fitted into the shaft 20.

conduit 3i together as a unit. Threaded uponthe forward end of the conduit 3| is a nozzles38. whose.

cone-shaped aperture 39 communicates'directly.

with the hollow portion of the conduit 3 I. Radial J apertures 49, it are provided in said nozzle 38 like manifold casing, designated generally as 52, i ;;which has adiameter substantially less than that of the casing [0 thereby to form an annular air passage ,therebetween. This head or casing is mountedzcoaxiallyof the shaft 20 and is provided withacylindrical; mixing chamber '53 which is formed concentrically of the head member. More specificallyjthis head comprises a rearward cirthereby to communicate with that space provided between the rotary shaft 20 and the conduit 3 l. r r.

' "The housing member '29 is normally connected withtwo separate sources of fluid supply under pressure. In the present case these separate supplies; contain liquid oil and steam respectively. Oil is introduced into a hollow portion. of the housing through a conduit 42, and then this oil passes into the plug 34 after first passing through a filter screen 43 which is secured over one 'end of the bushing 36 A radial bore 44, leading from the.hollow' portionof the plug 34 to a milled groove 45 formed longitudinally ofthe sleeve;33., leads the 'oil into the space provided between the conduit? and the shaft 20. This oil, still under pressure/is thus forced between the legs of the spider 31 and into the nozzle cone '39. through the medium of the radial ports 40, provided insaid nozzle.

Steam, under a-pressure higher thantha't which is provided for. the oil, gains entrance into the housing 29 by means of a conduit andthen passes into the; conduit 3|. by way ,of a milled slot 57 formed longitudinally in the s le eve 33.- This slot l communicates with the hollowlport io nof conduit 3! through a passage which is left open duelto the fact that the conduit 3| is spaced from the forward endof the plug34. Thus, the steam travels axiallythrough the conduit 3| to be discharged through the conical opening ,39 of the nozzle 38. As the steamthus passes through" this conical opening it is thoroughly mixedIwith' the oil issuing" into said opening by way 'of ,the" bores 4d, 4B and, therefore, the nozzle 38 func-- tionsto atomize the oil thoroughly before dis-' charging the same. 7 1 Spaced between the rearward end portion of. the shaft 29 and the housing 29 is a grooved labyrinth bushing 48. which functions as .a barrier for preventing the oil from escaping out of its normal path. Steam entering into the housing 29 finds its way into grooves 48 of the labyrinth 48, between the labyrinth and the shaftZfl, and therein condenses thus to function as a barrier for the oil. The steam, being forced into the housing under a pressure higher than that provided for the oil, will thus effectively prevent any oil escaping through the-labyrinth 48. g

By thus introducing the steam into the housing 29 about the oil conducting plug 34 and then forcing the sameaxially of the conduit 3|, two desirous results are accomplished First, as above dis-- closed, the steam. functions in the labyrinth 48 as: an-oil barrier, and secondly, the oil by surrounding the-steam throughout the major portion of the; conduit 3i, functions as anelfective 1 heat cula'rqwall 54 upon which is mounted a forward wall 55 by means of bolts 55.

flhe, spacing, provided between these walls '54 and 55 forms thefabovenoted mixing chamber 53. IReferring particularly toFigs. 1, 3 and .6, the

forward-Wall 55 of therotary head has provided thereon a1series"of' bosses 56' which are equidis-T tantlylspaced frornthe center of. the head and which are disposed inithe; same angular direction. Each; of these bossesjislprovided with an' aper-f ture 51. into which isfthreaded nozzle element 58 containing an orifiee {59' which'communicatesf with ,thelmixing chamber 531 Referring ,pa rticu larly to Figs. 4 and .6,'it i'sto be uhderstoodjthat eajcli'of these nozzles'is disposed upon the wall 55;

soas tjo'fo'rmjan acute angle therewith and to be? disposed substantiallytangentially of the wall a 55. Thus, lthejatomized' oil which is ejected from the nozzle'38 is forced, into the chamber 53 andout of each" of' the orifices 59 at an angle such that the head 52 will rotate'in a counterclockwise l dir'efctioii'un'der the reaction force of said jets- It istobeunderstood that such rotation of theheadjwill-carrywithit the shaft 20- and conduit Provided bathe flanged peripheryof the iwau member 55 are a plurality o'f-fan, blades 60 which are disposed in a manner such that when rotated, ablast of airfwill be caused toflow axially of said casing gr ndma direction towards the furnace t'e which' thecasing is secured. it At the rearwardend of the casing I0 is disposed an ai'r' metering unitorf register 6L which forms no part; offthe present invention and is not herein disclosed in detail; It sufficient tq say that this metering. unitjor register functions to vary the quantity of air which the, fan blades 60 may draw into the casing.,.; I j

The present 'bu'rneris adapted to be secured to a furnace or. boiler by means of a flange lfl'and the air blast caused by the fan blades 60 is forced in a directionft'owards said furnace in an annular shaped' path due tofth'e. presence of the rotary head axially disposed within the casing I 0. .Thus, thenozzl-es 58 are; disposed entirely on the leeward side of the rotaryheadand at points comout. of each nozzle in apathiindicated by pat-a ternlines 62. Thus, the jet from eachnozzleis projectedinto'theairstream from a direction substantially at right angles to the direction of' formed. Furthermore, 'as the nozzles themselves donot project into the air stream,; amost deg,

The dead'air 'spacebetween the plate 63 and wall 55 functions to limit the amount of radiant heat received within themahifol'di 1 The present invention may alsolbeincorporated in that type of rotary burner which employs oil and gas-as a fuel and' st'eafii' as an atomizin'g medifl'mfor the oil. Figs. 2, 5 ai:1'd""7- illustrate such a burner'construction. p

Referring particularly to Fig. 2, it is to be understood that this second burner construction is similarit'o that of the first 'infso' far as the general construction of the casingJournal box, and rotary shaft areconcerned. Therefore, the similarcjorresponding parts of the two burners have been'similarly numbered. The following description, therefore,- I will concern itself only with those parts of the second-burner which'are different from thoseof the first burner.

Gas under pi es'sure'is delivered into the hollow portion of the"housing-'2 9 through a pipe 33.

Front-the hollow portion 9! of the housing 29- the' gas will" flow forwardly-to enter the passage provided" between theshaft 20 and the conduit 1?. thereby to'su'rround"both the steam and oil passageways.

Rigidl'y mounted'npon the shaft 2t, at the furnace: end thereof is "a rotary fluid-distributingheadgenerallydesignate'dby the numeral 92 This head 92 comprises aback wall" member 93' -Car1 ied"rigidly'within the" opposed" hollow end "in the form of a cylindrical disk which is se-v cured by means of bolts a l to aring 95 welded upon 'thefurnace end of the shaft 28. A bafiie plate 95 having an, annular peripheral portion,

97' iscarried upon, theback wallmember 93 by bolts ea As be see from Fig. 2, the baffle plate as s mounted concentrically Within the casing l0" and its peripheral portion 9? has a diameter substantiallyjl'ess' thanthat of the casing lil thereby to form therewith: an annular air passageway. Extending outwardly-aria radially M ii r'iiea" withii'i and? coaxial or iiie conduit -The-fforward;portiin of tli econduitlfij isf 'th'reade'd into thehollow rearward" portion of to an" annular passage from the peripheral portiongSI is;a plurality of;

fan blades 99 which are designed to forceair axially of thecasing I0, past the fluid-distributing head 92, and toward the furnace. Moun ted upon the furnace side of thebafile plate 96 is a disk I which'forrns with the baflle 96 a cylindrical manifold I 0|. The screws I02 secure the diskI00 against the baffle 96. Formed about the face of the disk I00 .adjacent the periphery thereof are a plurality of projectin bosses I03 each of which isanguIarIy disposed relative to the face of the disk I00 at points equidistantly spaced from the center of the disk. Provided in each-,one of. these bosses is a nozzle I04 having an orifice I05 which is substantially disposed at.

an ;acute angle relative to the face of the disk I00. Mounted upon the face of the disk I00, by means of pins I06, is an insulating plate I0I. This plate is adapted to be spaced from thedisk I00 thereby to provide an air space therebetween for the purpose of preventing too much radial heat from the furnace from being absorbed by the fluids within the head 92.

Referring particularly to Fig. 2, it is to be understood that the head 92 essentially comprises a stepped hollow disk disposed coaxially of and mounted for rotation within the casing ID. The disk I00, projecting outwardly from the nozzlecontaining portion of theperipheral portion 91, forms at the junction of these two elements a step, and the baffle plate 96 thus forms a pair of axially spaced cylindrical manifold cavities ml and MB, of which each cavity is disposed within a respective stepped portion of the head or disk.

Provided between the disk 96 and the back wall 93 is a manifold chamber I08 which is substantially of circular shape and which is disposed coaxially of the casing I0. Communicating with this manifold I08 are a plurality of orifices I09 each of which is provided within the face of the disk 96 at points equidistant from the center of the casing I0. Each of these orifices is disposed in parallelism with the orifices I05 which are provided in the nozzles I03. Fluids, issuing under pressure from the orifices I05 and I09, cause, by reaction against thehead 92, the rotation of the entire head 92 about the axis of a casing I0. This rotation will be effective to force air axially of the casing I0 by means of the fan blades 99. I

The gas which is conducted through the pasjet reaction rotate, in cooperation with the gases; j

,, are discharged-into the annular shaped air pat-: i

e m or c sd s o ub t tially alright:

sageway formed by the tube 20 and the conduit 7 into the path of the air which is forced through the casing I0. The oil following along the passage defined by the spaced conduits I2 and I5 will pass about the rearward portion of the nozzle I6 and thus be inwardly and radially discharged into a conical portion H0 of the nozzle by way of a plurality of radially disposed'bores III formed in the nozzle I6. The atomizing steam forces its way through the conduit 15 to be discharged into the manifold IOI by wayof the conical passageway IIO provided in the nozzle I6. Thus it is to be understood that the oil and steam will be thrown into violent contact with each other within the conical passageway I II) to the end that steam will be effective to,

atomize the oil as the latterjisbeing discharged into the manifold l'0l. The atomized oil will then issue from each of the orifices I05 and by angles to the direction of flow of air, thus'to; ef feet a complete mixture of oil, gas and air; v .Disposed axially of the nozzle I 6 is a relatively short hollow tube II2 formedwith an; enlarged head; portion, II 3 which is secured-within both;v the plate I01 and thedisklllfl. Igocated-bctween-s the plate I01 and. the disk I00 and within thehead II3 are a plurality of radial bores H4, I M, which communicate with the hollow portion ,of;,

thetube for the purpose of delivering-steam-between the plate I0! and the disk I00: This steam, functions as an insulator to the extent :thatit will limit the amount of radiant heat trans-w ferred from' the combustion chamber ofthefurnace to the fluid-distributing manifold. 1. 'From the above description it is to be .under stood that thepresent fiuid-distributinghead substantially comprises a disk-like head having a, pair. of axially spacedcylindrical manifold,- cavities IM and I08separated by means of the baffle plate, said manifold cavities being in communication with a respective one'ofthefluid conduits formed by the concentricallyspaced tubes I2 and I5, and the'shaft 20, -Ejach of these 5 manifold cavities has in communication therewith a separate-group of fluid-atomizing nozzles; carried by the leeward or furnace side of the disk for the purpose of discharging therefrom jets of fluid which will, by reaction, effect a-rotati on of thedisk. r I.

It is to be further understood that Fig. 2 discloses only a preferred form of a'dualtmanifold construction and thatthe specific forrngofthis construction could be modified without going out;

valve I I8 which, when opened along with the by-;

pass valve H5, permits steam to pass, by wayof bor I'I'9, through all of the gas and oil passage-i ways for the purpose of cleaning the same preparatory to shutting down the burner unit f Referring to Fig. 1, the housing member 29 is, like the valve box I3, provided with a scavenging valve I20 which, when opened, permits steam to enter through a bore I2 I into the oil passageways forthejpurpose of cleaning the same.-
